New feature: In Illustrator versions which support canvas rotation (25.3 and above), you can now keep the constrain angle locked to the opposite of the canvas rotation angle, so you can draw orthogonally to the screen regardless of the canvas rotation.
Improvement: The panel no longer shows vanishing points that are extremely close to each other as "mixed".
Bug fix: Entering an angle in the Offset dialog for Drop Shadow or Transform live effects now correctly calculates the horizontal/vertical equivalents.
Bug fix: Positioning of spot/global color badges on panel chips is now correct.
Improvement: The Arc by Points tool can now indicate when the start or end point of the arc is snapping to the endpoint of an existing path.
New feature: When joining to an existing open path, the Arc by Points tool can now snap to angles at which the arc continues the path in a tangent manner.
Bug fix: The Arc by Points tool no longer crashes when attempting to draw an arc indicated as "Too Large" with joining enabled.
New feature: Shift-clicking on “Break Text into Lines” now breaks it into paragraphs.
New feature: “Type > Remove Line Breaks” menu command.
Improvement: “Remove Paragraph Breaks” now works on selected text only.
Improvement: “Remove Paragraph Breaks” is now actionable.
Improvement and bug fix: When combining lines of text with Space Before/After attributes, the values are now retained (when possible) and the spacing after the first line is now correctly calculated.
Bug fix: Attempting to break a text box consisting entirely of return characters into words no longer causes a crash.
New feature: The Dynamic Measure tool can now be forced to make a measure transient (automatically disappearing after a set time) regardless of the current mode, by holding down Option/Alt when finishing the measure.
Bug fix: The Path Intersections command no longer erroneously removes the last segment of an open path when "Add Points to Paths" option is used and the intersection is not in the final segment of the path.
New feature: Applying a Reform with either the Apply panel button or the Enter or Return key, holding down Option/Alt retains the original artwork and a new path of the reshaped section is created

Improvement: The changing of key modifiers whilst click-dragging out the initial reform allows the Reform mode to be altered instantly between standard (no key press), Looped (Option/Alt) or a Constant (Shift + Option/Alt) Offset modes
